Re: [xsl] embedding XML in the value of attribute

Seconding Michael's comments on this --

The JSP syntax is not XML, even though it bears a passing resemblance to it.
If you are using JSP in this fashion - to pass the results of a Java class
to an output stream, however, it may be worth your while to recast the whole
page as an XML document  processed by an XSLT document with an appropriate
handler for the tag:

Your XML source document may then look like:

<html>
    <head>...</head>
    <body>
        <form ..>
            ....
             <larry:formclass id="myinput"
xmlns:larry="urn:schemas-larry-com:formclass"/>
    </body>
</html>

Your XSLT transformation may look like:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                      xmlns:larry="urn:schemas-larry-com:formclass">
    <script language="Java" src="larry.formclass"
implements-prefix="larry"/>

    <xsl:template match="/">
        <xsl:apply-templates select="*|@*|text()"/>
    </xsl:template>

    <xsl:template match="*|@*|text()">
        <xsl:apply-templates select="*|@*|text()"/>
    </xsl:template>

    <xsl:template match="larry:formclass>
        <input type="text" name="{@id}" value="{larry:getInput()}"/>
    </xsl:template>
</xsl:template>

The advantage to this approach is that you can also pass parameters to the
input type via attributes, something that is more problematic using JSP.
Take a look at Michael's superb book for more information on using extension
functions.
